[Changes in the parameters of humoral immunity due to surgical operations or trauma].

Humoral immunity (immunoglobulins and C3) as well as nutritional conditions (serum albumin, transferrin) have been investigated in 23 patients in the acute phase after surgery and/or trauma. Immunoglobulin deficiency, well correlated with the severity of trauma, was observed in the most critically ill patients in the very early phase, followed by a rapid rise to near to normal values and typical immunologic response. There is no evidence that this depression of humoral immunity may enhance the risk of infectious complications in the postoperative period.

[Correlations between gastric erosions and duodenal ulcer. Endoscopic study].

123 varioliform, 105 aphthous and 48 haemorrhagic flat erosions were noted in 2618 gastroduodenoscopies. A high incidence of erosions were associated with duodenal ulcer (43% of duodenal ulcers), especially in varioliform types and antrally. It is suggested that antral varioliform erosions form an integrating part or even the sole expression of an ulcer, and thus be seen as "sentinels" of an existing, potential or prior duodenal ulcer.
